Oldest-ever meteorite found in Africa… and could unlock the solar system’s secrets

The oldest meteorite ever discovered by scientists could help researchers on their quest for truth and how our solar system formed 4.6 billion years ago. The record breaking space rock was discovered in Mauritania, Northwest Africa.

Found in a sand dune in Mauritania, the light-colored space rock is laced with green crystals and is about the size of a baseball.

Fondly nicknamed ‘Northwest Africa (NWA) 11119’, the rock is believed to be 4.565 billion years old. Scientists believe our solar system was formed 4.6 billion years ago – not too long before our newly-discovered sky pebble from above – when a gas and dust cloud collapsed due to gravity, possibly due to the final, star-ending explosion from a nearby supernova.

An audio-visual device for the blind invented by Syrian students

Supervised by Dr. Carlo Makdisi, Eng. Ziad Hammoud and Amjad Hassan, who are students at the Faculty of Mechanical and Electrical Engineering in Tishreen University in Lattakia Governorate, design an advanced ultrasonic device for the blind as to help them overcome obstacles.

The device was presented for the first time at the” Applied Projects Exhibition”, which has been  recently held at the Faculty of Mechanical and Electrical Engineering in Tishreen University in Lattakia.

Boys more 'cliquey' than girls

Whether it's due to popular teen films such as Mean Girls or gender stereotypes most people imagine girls form more cliques than boys.

Yet a new study contradicts this, suggesting that boys are more likely to form tight-knit friendship groups, according to BBC.

Researchers say analysing social mixing patterns is important for infectious diseases and vaccination planning.

They found that boys were more likely to mix with the same six friends over a period of six months.

Galaxy outskirts likely hunting grounds for dying massive stars and black holes

Findings study provide further evidence that the outskirts of spiral galaxies host massive black holes. These overlooked regions are new places to observe gravitational waves created when the massive bodies collide, the authors report.

The study winds back time on massive black holes by analyzing their visible precursors -- supernovae with collapsing cores. The slow decay of these massive stars creates bright signatures in the electromagnetic spectrum before stellar evolution ends in black holes, according to Science Daily.

Black holes DON'T have a ring of fire, new study suggests: Scientists say they instead may act like a giant 'fuzzball'

 A new study is challenging the idea that black holes are surrounded by ring of fire that incinerates anything in their path, according to Daily Mail.

According to new calculations, black holes may act more like balls of string, meaning they accumulate more and more ‘fuzz’ as objects are pulled in.

The scientists say this means the fuzzy surface would extend to meet the object well before it reaches the hottest part of the black hole.
